A guy is feeling depressed and goes for a walk on the beach.

He finds an old bottle on the shore, and when he picks it up a spirit comes out and says, "You look tense. Would you like a good back rub?"

"Well, actually, I'm depressed because I'm so broke. I wish you would give me a million dollars instead."

"I can't do that, but I can give you a back rub."

"Aren't genies supposed to grant wishes?"

"I'm not a genie. Does that look like an oil lamp? And you call what you did rubbing it? I'll show you what a real rub is!"

"If you're not a genie, what are you?"

"Haven't you ever heard of a massage in a bottle?"
